Jose Mourinho’s Chelsea marched into the Champions League last 16 as Group G winners on Tuesday after their emphatic 5-0 win at Robert di Matteo’s Schalke 04.

Mourinho’s Premier League leaders brushed Di Matteo’s ineffective Royal Blues aside in Gelsenkirchen as captain John Terry put them ahead within just two minutes of the kick-off.

Further first-half scores by Willian and an own goal from defender Jan Kirchhoff were followed by second-half strikes from Didier Drogba and Brazil midfielder Ramires.

“I am very happy, it was a very impressive performance,” beamed Mourinho.

“We weren’t coming here to see if a point would be enough to put us through and we showed that from the first minute.

“It was 90 minutes of good football.”

The result matched Schalke’s record European home defeat when they were hammered 6-1 by Real Madrid in last season’s round of 16, first leg, in February this year.

Chelsea remain unbeaten in all 19 matches this season and are now four points clear in the table ahead of their final match at home to second-placed Sporting Lisbon in a fortnight.

Di Matteo’s unbeaten home record after four wins was ended by his former club in brutal fashion.

“It was already a difficult evening for us and we made it even harder by conceding so early,” said Di Matteo, who apologised to Schalke fans for the performance.

“I was surprised by our lack of confidence, we weren’t aggressive enough and we gave them far too much space.

“We have to look ahead now and put this behind us as quickly as possible.”

Schalke drop to third, having been leap-frogged by Sporting who won 3-1 at home to Maribor, who they must beat in Slovenia in their final game next month to stand any chance of progressing.

“It’s hard to find words for this,” said Schalke captain Benedikt Hoewedes.

“I can only apologise for our performance.

“We gave Chelsea too much space to play. They are so good individually and we let them score too many goals.”

Di Matteo, who is just eight games into the Schalke job, remains the only Chelsea manager to win the Champions League and Mourinho refused to even talk about him in the match’s build-up.

The self-styled ‘Special One’, who won the Champions League with Inter Milan in 2010 and Porto in 2004, is bidding to win the European crown at the fifth attempt with Chelsea and his side dominated their hosts in Gelsenkirchen.

Chelsea needed less than two minutes to take the lead at Schalke’s Veltins Arena.

Eden Hazard put Diego Costa away and the Spain striker tested Schalke goalkeeper Ralf Faehrmann, who palmed his shot away.

Cesc Fabregas floated in the resulting corner from which Chelsea captain John Terry rose highest to head home barely challenged.

Cameroon striker Eric Choupo-Moting gave Schalke brief hope on 13 minutes when his shot deflected off Gary Cahill’s boot and looped over Chelsea goalkeeper Thibault Courtois, but it clattered off the bar.
